On Harlan's World, you don't see many mandroids. They're expensive to build, compared to a synthetic or even a clone, and most jobs that require a human form are better done by those organic alternatives. The truth is that a robot human is a pointless collision of two disparate functions: artificial intelligence, which really works better strung out on a mainframe, and hard-wearing, hazard-proof bodywork, which most cyberengineering firms designed to spec for the task at hand. The last robot I'd seen on the World was a gardening crab.
